Applicationfiled November 9, 1925. Serial No. 67,728.

This invention relates to improvements in dolls and has as one of its objects to provide a doll havingpivotally jointed arms so arranged as to assume different positions in accord-ance with the posture of the doll body.

A further feature of the invention resides in the application of a removable object'to the hand of one arm, whereby an object, such as a simulation of a nursing bottle is automatically moved towards the mouth of the doll when the doll is disposed in a reclining position, andmoved away when the doll is upright.

Another aim is in the provision of simple,

gravity operated means for actuating the arms into their various positions, the mechanism being of inexpensive construction, readily assembled within a doll body and capable of withstanding the severe use and handling to which such dolls are frequently subjected. These objects are accomplished by the novel construction and combination of parts hereinafter described and shown in the. ac-

compayin drawing, forming a material part ofthis disclosure, and in which Figure 1 is a partial side elevational, par-. tial sectional view of the head and bust of a doll showing the application of the invention.

Figure 2 is a front elevational View of the same. Y i V Figure 3 is a view similar in all respects to Figure 1 but showing the parts in another position.

Figure & is a fragmentary sectional view showing the method of attaching the arms to thebust and the means for actuating the arms.

Figure 5 is another view like Figure 1, but showing an alternative actuating means for the arms. V

Figure 6 is a fragmentary front and sectional view showing one of the arm connections.

A conventional type of doll head is designated generally by the numeral 10, the same presenting the usual features and is of hollow construction, being made of papier-mach or similar material in molds or dies, this head being integrally connected by aneck 11 to a bust 12 terminating in a level plane below the shoulders 13.

These shoulders are provided with flatwalls 14 arranged in parallel and have passing through them circular openings 15 disposed in alinement and in which the arms are pivoted. Y p The arms 16 and 17 respectively right and left are bent at the elbows at substantially right angles, the forearms terminating in hands18 and 19; y w t j v Both arms are'so shaped as to present flat surfaces at their shoulder juiiction'portions to agree with the corresponding surfaces 14, and are provided with round studs 20, rigid- I 1y; fixed-in the arms to extend through the openings 15 and engage in the ends of a tube extending between them within the confines of the bust, the 'ubebeing'pinned or otherwise filjlk'lly secured to'them.

Fixed centrally onthe tube 21 is an arm 22 having a weight 23 at its free end, this I weight being free to swing within the space between the walls at the throat or neck of the doll, shown best in Figures 1 and 3, which indicate two different positions of the arm. s

In Figure 5 thearm and weight are omitted and a short' pendant arm 23 secured to the tube 21, this arm being in position to be engaged by the short end 24 of a lever, the long, pendant end 25 of which carries a weight 26, the lever being pivotally supported by a pin 27 set in the bust as shown. Clearly the weights will move by gravity in the direction indicated by the arrows when the doll is laid down and operate to raise the arm or arms towards the'head.

If it be preferred that only oneof the arms be moved, the arrangement shown in Figure 6 may be used. In this case the stud 20 may be fitted closely to the opening in the bust, the inner extending end of the stud rotatably engaging the end of the tube and heldtherein by a pin 28fixed in the stud and operatively engaging a slot 29 in the tube 21.

The primal idea of the invention is to simulate as closely as possible the action of an infant in moving a nursing bottle to its mouth when laid down and, conversely, when. raised to an upright position, to take the bottle from its mouth in a natural main 7 ner, both of which features are disclosed in an obvious manner. I

It is also regarded desirable to be able to remove the bottle 30 entirely from the hands. the left hand 19 being preferred, and this hand, including the fingers 31 and thumb 32,- are so shaped as to constitute a conical socket or holder in which the bottle may be entered or removed at Will.

As changes of construction could be made Within the scope of the invention, it is intended that all matter contained in the foregoing description or shown -in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is 2- 1. A doll having a hollowbust flattened at the sides and containing openings in its side Walls, a pair of arms having fixed studs revolubly mounted in the openings, a tube rigidly connecting said studs, a lever on said tube, and a Weight on said lever, said Weight being freely movable Within the bust upon change of position thereof.

2. A doll comprising a hollow head and bust, a pair of arms havingffixed studs revolubly mounted in said bust, a tube connecting the inner extending ends of said studs, one of said studs being fixed in the tube, the other stud being rotatable in the tube, means to confine the rotatable stud Within the tube, and means including a weight and lever to rotate said tube.

8. A doll comprising a hollow head and bust, a pair of arms having fixed studs revolubly mounted-in said bust, a tube conrying arod rigid herewith, said rod journalled In said body, a weight mounted upon said rod ina position displaced .fromgthe axis thereof, forming a bell-crank With said arin and solely controlling the movements.

thereof whereby upon change of position of said doll to change theposition of said arm. i

In testimony whereof I have signedsmy name to this application.
